My question is how would my deceased father's current spouse of only 6 months of marriage , be able to obtain 1/3 ?

I'm 1 of the heirs out of 6 heirs in my father's intestate estate case. My case consist of 6 heirs , my Father's current spouse of only 6 months of marriage prior to his death and my father's ex wife whom he divorced a year prior to his death , when the divorce was finalized, 2 marital properties were in current litigation proceedings which property assets were not split during the divorce of a 34 yr marriage. My father's current spouse of 6 months, was only a living tenant with my father on 1 of the properties from his prior marriage in litigation and it was a business property with an adjoining living space within the building of the property which was acquired in his prior marriage. The spouse of 6 months has no children or property assets with my father , but she seems to feel that she gets a share of 1/3, which she also has a prior federal case which she owes 4.5 million in restitution for her crimes. So I can't understand why the current spouse feels so entitled.
